An electronic warfare software system design for an electronic counter measures system is presented which includes two general purpose processors GPP and multiple special purpose processors SPP. The GPPs are the system controllers. These GPPs transmit setup data, including time information or hardware item and all related tasks for that function or hardware item. The SPPs are not required to handle multiple tasks and therefore do not require high complexity design. Also the complexity of the GPPs is reduced. The requirements of the system could be met by each SPP, keyed off a central clock strobe, with the resources of the processor dedicated to satisfying that functions time critical needs. In the two GPP setup the GPPs retain central control as well as completing overhead type tasks. There is one central executive control function that allocates tasks to be done to each of the processors. All the SPPs are addressable by either of the GPPs and the GPPs share an instruction and data memory fetch arbitrator.
